Abstract

Purpose: This study aimed to develop a motor-free short-form of the Wechsler Intelligence Scale for Children – Fifth Edition (WISC-V) that allows clinicians to estimate the Full Scale Intelligence Quotients of youths with motor impairments.

Method: Using the reliabilities and inter-correlations of six WISC-V motor-free subtests, psychometric methodologies were applied to develop look-up tables for four Motor-free Short-form indices: Verbal Comprehension Short-form, Perceptual Reasoning Short-form, Working Memory Short-form, and a Motor-free Intelligence Quotient. Index-level discrepancy tables were developed using the same methods to allow clinicians to statistically compare visual, verbal, and working memory abilities.

Results: The short-form indices had excellent reliabilities (r = .92 - .97) comparable to the original WISC-V.

Conclusion: This motor-free short-form of the WISC-V is a reliable alternative for the assessment of intellectual functioning in youths with motor-impairments. Clinicians are provided with user-friendly look-up tables, index level discrepancy tables, and base rates, displayed similar to those in the WISC-V manuals to enable interpretation of assessment results.
